There's such discussion regarding whether such converter is implemented or not
(this is composed by Vipuser according to the page history), however Node ue
and I disagree with these because there will be some problem if such converter
is being implemented. See also the talk page for Node ue:
http://commons.wikimedia.org/wiki/User_talk:Node_ue, and Vipuser argues with
that issue.
